Constructors of Multiple Inheritance
Constructors of Multiple Inheritances:
When a class is derived from more than one base class, the constructor of the derived class as well as of all its base classes arc executed when an object of the derived class is created.
If the constructor functions have no parameters then first the constructor functions of the base classes are executed and then the...
Multiple Inheritances
Multiple Inheritances:

Multiple inheritances are a powerful feature of Object Oriented Programming. This technique reduces the program size and saves programmer’s time. The programmer uses...
Derived Class Constructors
Derived Class Constructors:
In inheritance, a constructor of the derived class as well the constructor functions of the base class arc automatically executed when an object of the derived class is created.
The following example explains the concept of execution of constructor functions in single inheritance.
Program:
#include <iostream.h>
#include...
